Angular $resources Cancel requests : $q - angularjs

Question

I'm trying to understand...
How can I implement a requests cancell for this kind of services.
I was reading, that I shoud use $q.defer()
angular.module('App').service('TService', function ($resource, portal) {
return $resource(portal.getUrlServer() + 'api/T/:id', { id: '#Id' }, {
T_GET: {
method: 'GET',
params:{
id_turno: '#id_turno',
},
url: portal.getUrlServer() + 'api/T/T_GET/'
},
G_GET_Turno: {
method: 'GET',
params: {
id_tramite_relevado : '#Id_Tramite_Relevado'
},
url: portal.getUrlServer() + 'api/T/G_GET_Turno/'
},
});
What I want to do is when any method is called twice, I just want to let run the last called and cancel the other requests.

From AngularJS docs:
If an action's configuration specifies that it is cancellable, you can cancel the request related to an instance or collection (as long as it is a result of a "non-instance" call).
// ...defining the `Hotel` resource...
var Hotel = $resource('/api/hotel/:id', {id: '#id'}, {
// Let's make the `query()` method cancellable
query: {method: 'get', isArray: true, cancellable: true}
});
// ...somewhere in the PlanVacationController...
...
this.onDestinationChanged = function onDestinationChanged(destination) {
// We don't care about any pending request for hotels
// in a different destination any more
this.availableHotels.$cancelRequest();
// Let's query for hotels in '<destination>'
// (calls: /api/hotel?location=<destination>)
this.availableHotels = Hotel.query({location: destination});
};
